The Warrior Infantry Fighting Vehicle has the speed and performance to keep up with Challenger 2 Main Battle Tanks over the most difficult terrain, and the firepower and armour to support infantry in the assault. A highly successful armoured fighting vehicle, Warrior can be fitted with Enhanced Armour and is continuously being updated; for example, the Battle-group Thermal Imager (BTI) is being fitted to increase its night-fighting capability. Warrior infantry command and section vehicles carry a turret mounted 30 mm Rarden cannon that will defeat light armoured vehicles out to 1,500 m. An 8x magnification image-intensifying night sight is fitted, and eight 94 mm Light Anti-Armour Weapon (LAW) HEAT rockets can be stowed in the vehicle.

Warrior variants include artillery observation post vehicle (OPV) and command post vehicle (CPV), and a Royal Mechanical and Electrical Engineers (REME) recovery and repair vehicle. All variants are equipped with a 7.62 mm chain gun. Both chain gun and Rarden cannon have an anti-helicopter capability.
